Answer:

29, 32, 48, 58, x, x + 2, 64, 78, 84, 90.

begin mathsize 12px style fraction numerator straight x plus straight x plus 2 over denominator 2 end fraction equals 63 end style

126 = 2x + 2

2x = 124

x = 62

observations are

29, 32, 48, 58, 62, 64, 64, 78, 84 90

As highest frequency = 2(Since 64 occurs 2 times)

Mode = 64
